IM PROVEMENT m' CRAYONS.

Specification forming part of Letters Patent No. 196,054, dated October 9, 1877; application filed April 28, 1877.

improved crayon, and Fig. 2 a transverse section.

In the drawing, Arepresents acrayon made of chalk or other suitable material, and of any color, and of the usual shape, and otherwise all as ordinarily.

This crayon A, I surface exteriorly, and either for the whole or only that portion, B, of its length by which the crayon is handled in use,

with a liquid solution, by preference of gumtragacanth, although, as will hereinafter appear, other material may be used, by dipping the same in such a liquid solution, or applying the solution in any suitable manner, and afterward allowing it to dry upon the crayon.

This coating-surface of the crayon seals the crayon against soiling the fingers of the per son using it, while at the same time its nature is such as to freely wear away with the wear of the crayon in its use, all as is obvious with out further description.

For the gum-tragacanth, in its use as above described, other gums, varnishes, sizings, dyes, bronzes, paints, glycerine, paste, glue, starch, &c., may be substituted and. obtain the result aimed at by this invention, and therefore I do not intend to limit myself to any particular material or combinations of materials to surface a crayon for the purpose described, although, as I have before said, I prefer gumtragacanth.

Having thus described my invention, what Iclaim, and desire to secure by Letters Pat= cut, is-

As a new article of manufacture, a crayon having its exterior surface coated with a solution of gum-tragacanth or other similar mate rial, for preventing the crayon soiling the fingers, as herein set forth.
